Summary
A rare congenital perineal lipoma presented as a newborn anal mass. Surgical excision confirmed mature fat cells, highlighting this benign condition
Area of Science:
- Pediatric Surgery
- Dermatology
- Medical Imaging
Background:
- Congenital perineal lipomas are rare tumors presenting at birth.
- Prenatal imaging often struggles to definitively diagnose these lesions.
- Differential diagnoses include teratomas, cysts, polyps, and other perineal tumors.
Observation:
- A newborn presented with a 2 cm pediculated mass on the anal margin.
- Antenatal sonogram and MRI were inconclusive regarding the lesion's exact nature.
- No other congenital anomalies were noted at birth.
Findings:
- Surgical excision of the para-anal mass was performed under general anesthesia.
- Histological examination revealed the lesion to be a mature lipoma.
- This case adds to the limited literature on congenital perineal lipomas.
Implications:
- Congenital perineal lipoma is a rare, benign condition.
- Early diagnosis and surgical excision are effective treatment options.
- Advanced imaging like MRI can suggest the diagnosis, aiding in management.
